snort Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed September 17, 1915. Serial No. 51,223.

To all whom it may concern.

Be it known that I, EVERETT H. DUNBAR,

a citizen of the United States, residing at Lynn, in the county ofSuffolk and Commonwealthof Massachusetts, have invented a new and usefulImprovement in Shoes, of

which the following is .a specification.

- My invention relates to a type of shoe designed for the correctivetreatment of the foot, such as the restoration of fallen or brokenarches, and ithas been the special object of my invention to provide ashoe which may accomplish this resultwithout the use of an independentmember such as a removable arch support.

It has been the further object of my invention to so design andconstruct a shoe that the corrective means may be quickly and easilyadjustable so that it may be adapted to the particular and varyingrequirements of the wearer. This I accomplish by means of a pocket inthe inner sole provided with an aperture through which padding materialmay be inserted.

My invention may be best understood reference to the accompanyingdrawing in which-J I Figure I is a top view of the inner sole I of theshoe with the padding pocket and its metal support indicated by dottedlines Fig. II. is a vertical cross section online 22 of Fig. I. Fig. IIIis a longitudinal cross. section of a shoe provided with my device.

Referring now more specifically to the drawing A is the inner sole of ashoe provided with the usual sole B and the upper C. Beneath the innersole is stitched a piece of leather, canvas or other suitable materialD, thereby forming a pocket which isindicated by the dotted line (i ofFig. I. Entrance may be had to this pocket through the slot d in theinner sole A. It will be apparent to those familiar with the artthatthis pocket is located beneath the transverse arch which is to betreated in the shoe asbe inserted by means of a small pair of plierspadding G for which I preferably employ curled horsehair, although wool,cotton orother material may be used, thus forming a boss or pad whichsupports the bones of the arch of the foot of the wearer which requirecorrective re-placement. This pad so formed is'preferably supported by athin plate of steel or other suitable metal E, shape of" which is bestdisclosed by the dotted line 6 in Fig. I, where it will be seen to beelongated so as to form not only a support for the pad but also theusual shank which is commonly used in shoes although '-many shoes arenow made with a flexible sole which does not include a metallic shank,and it is to be understood that I do not in any way limit my inventionso as to include a metallic member of the form indicated. This metallicmember E may be provided with holes F through which it may be tacked tothe wooden last so that it-may be held in place in the process ofmanufacture.

While I have shown in the form of my invention as disclosed in thedrawing a pocket formed by stitchingthe member D to the end sideof thesole it will, nevertheless, be apparent that if a very thin and flexibleleather or other suitable material be used the pocket might well beformed by applying this member to the upper side of the innersolewithout departing from the scope of my invention.

It will be. readily understood from the foregoing that there is formedin the innersole a boss or pad for the corrective treatment'of the bonesof the foot which is not subject to displacement and which will besufliciently yielding to be comfortable and which will be capable ofchange and adapta: tion to the particular requirements of the wearer. Itis also quite possible by similar means to form more than one boss orpad in the innersole when the wearer of my improved shoe requirescorrective treatment in more than one part of his foot.

Having thus fully described my invention what I claim is' 1. A shoehaving an innersole attached thereto and a pocket in said innersoleprovided with an aperture in the top thereof through which paddingmaterial may be inserted or withdrawn.

2. A shoe having an innersole attached thereto, a pocket in saidinnersole, and padding material in said pocket, said pocket beingprovided with an aperture in the top thereof through which said paddingmaterial may be inserted or withdrawn.

3. A shoe having an innersole attached thereto, a pocket in saidinnersole, padding beneath said innersole in a manner whereby materialin said pocket, said pocket being a pocket is formed between saidinnersole provided with an aperture in the top thereof and said piece,a. slotted aperture in said inthrough which said padding material maynersole giving access to said pocket, padding 5 be inserted orwithdrawn, and a metal material in said pocket, and a metal shank l5shank in the sole of said shoe, said shank in the sole of said shoe,said shank being exbeing extended to form a support for said tended toform a support for the pad padding. I formed in said pocket.

4:. A shoe having an innersole attached i 10 thereto, a piece ofsuitable material fastened EVERETT H. DUN BAR.
